%description
Diffusion Weighted Imaging (DWI) is a Magnetic Resonance Imaging modality,
that measures diffusion of water in tissues like the human brain. The
package contains R-functions to process diffusion-weighted data. The
functionality includes diffusion tensor imaging (DTI), diffusion kurtosis
imaging (DKI), modeling for high angular resolution diffusion weighted
imaging (HARDI) using Q-ball-reconstruction and tensor mixture models,
several methods for structural adaptive smoothing including POAS and
msPOAS, and a streamline fiber tracking for tensor and tensor mixture
models. The package provides functionality to manipulate and visualize
results in 2D and 3D.
